Dimensional Tolerance Tables
Center to Center Tolerances
Tolerances are proportional to linear distances as shown below:
| Center to Center dim |
Tolerance |
1.0" or less
1.0"-2.0"
2.0"-4.0"
4.0"-8.0" |
± .0002
± .0003
± .0005
± .0008 |
Linear Edge to Edge Dimensional Tolerances
Tolerances are dependant upon metal thickness as shown below:
| Metal Thickness |
Tolerance |
.005" or less
.006"-.015"
.016"-.025"
.026"-.040"
.041"-.062" |
± .0005
± .001
± .002
± .003
± .005 |
Note: As a general rule
the diameter
of a hole or the width of a through slot cannot
be less than the thickness of the metal. This may
vary with the
thickness and type of metal used.
